The key question for MQR is the dramatic drop of OSIs which occurred in the time 

 interval between the 1987 and 1991 REMOTS® surveys. This sharp, localized decrease 

 suggests a physical cause (such as trawling), perhaps exacerbated by adverse chemical 

 conditions. The presence of numerous mud clasts and rip-ups, and evidence of surface 

 erosion in the REMOTS® photographs of the 1991 survey support this conclusion. 

 Additionally, since this decrease in OSI values is not widespread among the mounds at CLIS, 

 the cause of the stress must be localized physical disturbance.
